Mobile Metrics Launches High Capacity 802.16e Base Station Test System

(Product News, 1 Apr 2008)

Mobile Metrics has released the Torrent 7220, which provides functional, stress, and performance testing for 802.16e Mobile WiMAX base stations, and which also allows for mobile station testing as it provides a complete end-to-end WiMAX ecosystem. The Torrent 7220 builds on the foundation established by its predecessor, the Torrent 7100, which was said to be the world's first commercial system for testing ASN Gateways and CSNs.

One of the key characteristics of the 7220 is that it supports thousands of mobiles per channel while still honoring QoS scheduling requirements, thus enabling testing of very high capacity traffic profiles while at the same time capturing detailed statistics that allow accurate characterization of the end user experience.

The 7220, to be showcased at the CTIA WIRELESS 2008 Conference in Las Vegas on April 1 to 3, uses a PHY-bypass mode following Intel's OFDMA PHY SAP specification, allowing very significant testing of base stations and mobiles to be performed, prior to completion of and independently of baseband/RF hardware. To address the critical issue of PHY and over the air testing, Mobile Metrics plans to release the Torrent 7240 next month, which will build on the 7220 by providing complete 802.16e PHY functionality.
